notes B2.1 Cells and Cell Structures Summary All living things are made up of cells. The structures of different types of cells are related to their functions. To get into or out of cells, dissolved substances have to cross the cell membranes. Cells Cells are the smallest unit of life. All living things are made of cells. Most human cells, like most other animal cells, have the following parts: o nucleus o cytoplasm o cell membrane o mitochondria o ribosomes Plant and algal cells also have:

Genetic Engineering: Designer Babies What if the world were free of genetic diseases, or if it was a place where parents could control their offspring’s height, hair color and intelligence? The science may be closer to being available then some people think. Genes sometimes interact in ways that human may never completely understand, so we never know what might happen. Society could become a place with designer babies, unforeseen genetic problems and a genetically enhanced society where only the

understanding the greater debate surrounding cloning. At the Roslin Institute in Edinburgh, Scotland, in July 1996, scientists produced the first animal cloned from an adult cell. Dolly the sheep was born early in 1997, shocking the scientific community and the world. Dolly was created through a process called cell nuclear replacement. A mammary cell of a six-year-old white Welsh Mountain sheep was transferred into the egg shell of a Scottish Blackface ewe (Calhoun Cash 2). Since Dolly’s birth, other species

Plant Cell Structures Instructions: Your lab report will consist of the completed tables. Label each structure of the plant and animal cell with its description and function in the provided tables. When your lab report is complete, submit this document to your instructor in your assignment box. 1. Animal cell: Observe the diagram that shows the components of an animal cell. Using the textbook and virtual library resources, fill in the following table: Animal Cell Number Cell Structure

of plants & animal cells are: * Mitochondria are where enzymes are, where aerobic respiration reactions take place. * Cytoplasm is a gel-like substance where anaerobic respiration takes place as some controlled enzyme reactions take place here. * Cell membrane is what controls what goes in and out of the cell as it acts like a barrier allowing water & gases to pass through easily. What does the bacteria cell consist of? * They have a simple cell structure of a circular

DNA. The ZFN protein complex is injected into a cell, and it attaches to the DNA and breaks the double helix in a specific place. Then, this cell repairs the damage by using another unbroken piece of DNA as a template for the broken strand. Gene editing tools including ZFNs make use of this type of repair system. Normally, the repair template used is the other chromosome, but gene editing tools can place a new template into the cell and have the cell change the DNA to the new template. This changes

Being a 17 year old female, I tend to interest myself in arguments that deal with controversial topics, that may affect my future or make me question my opinion. The act of taking already existing genetic material, and making an exact copy, is known as cloning. A revolutionary advancement, we are now capable of achieving with the technology and knowledge obtainable to us. When it comes to cloning, there is three types; therapeutic/research, reproductive human cloning and reproductive animal cloning

body structure units and their functions are: Cells, Tissues, Organs, and Systems. Cells Humans and all living things are made up of about 100 trillion small cells that can only be seen via a microscope. Cells can reproduce themselves and live independently. Some cells are specialized and become a different shape and size (elongated, oval, square, flat etc) dependant on its function. Here are just a few examples: * Epithelial cells – can be flat, cubed or column shaped. They protect
